High-hardness and wear-resisting low-carbon stainless steel material and preparation method thereof

Abstract

The invention provides a high-hardness and wear-resisting low-carbon stainless steel material. The high-hardness and wear-resisting low-carbon stainless steel material contains chemical element components in percentage by mass: 0.1-0.35% of carbon, 1.7-2.1% of manganese, 0.5-0.8% of niobium, 13.2-13.5% of chromium, 1.0-2.5% of antimony, 0.3-0.5% of arsenic, 1.0-2.5% of tin, 0.7-0.9%of silicon, less than or equal to 0.030% of P, less than or equal to 0.030% of S and the balance of iron. According to the high-hardness and wear-resisting low-carbon stainless steel material, the raw materials including antimony, arsenic, niobium and the like are combined, a proportion and a production process are reasonably set, and an adding sequence is reasonably set, so that a formed alloy material has a good comprehensive mechanical property, not only has excellent toughness and plasticity of low-carbon steel, but also has very high strength, hardness and wear resistance; the high-hardness and wear-resisting low-carbon stainless steel material also has an excellent corrosion-resisting performance; one part of waste iron is used as a raw material so that the quality of the alloy is stable and uniform; a refining agent is added, so that the porosity is reduced by 1-2 degrees. The stainless steel is applicable to various fields including containers, farm tools and the like.

Description

technical field [0001] The invention relates to the field of metal material preparation, in particular to a high-hardness wear-resistant low-carbon stainless steel material and a preparation method thereof. Background technique [0002] The development of alloy steel has a history of more than 100 years. So far, a variety of alloy steels have been applied in industry, mainly including the following types: quenched and tempered steel, spring steel, tool steel, high speed steel, die steel, high school Low-carbon alloy steel, etc., so far, although alloy steel technology has been greatly developed, there are still many problems, such as wear resistance, hardness, rust resistance, corrosion resistance, high and low temperature resistance, brittleness, toughness, Costs cannot be taken into account. In many cases, the production requirements cannot be met, and further improvements are needed to improve production efficiency, reduce costs, improve safety, provide guarantee for the ...
